Mansarovar Apartments: Resale liquidity is a major concern

Has anyone seen decent capital appreciation for Mansarovar Apartments since it launched? I'm finally done with renting, landlord ne rent badha diya fir se. Thinking of putting money into a completed project in Noida Extension. Mansarovar looks good, but I'm worried about its resale potential. Kya yahan liquidity achhi hai? Matlab, agar 5-7 saal baad bechna pade, toh easy hoga kya? Also, what's the actual rental yield people are getting here? Brochure mein toh figures alag hote hain, real mein kya milta hai?
